摘　　要：提出了一种基于正交调制的WDM-PON和RoF混合接入网方案。在该方案中,射频信号和单播数据被正交调制到光载波上。在接收端采用不同的解调方案,分别得到单播数据和射频信号。该方案实现了有线和无线宽带业务的融合。实验显示了该方案在低射频载波频率下能得到较好的误码率。A hybrid access network of WDM-PON and RoF based on orthogonal modulation is proposed in this paper. In the network, the optical carriers modulated by unicast data are remodulated by RF signal. Unicast data and RF signal are received through different demodulation schemes at the sink, respectively. This network realizes integration of wired and wireless broadband services. The experiment shows that the solution provides a good BER at low RF carrier.
